	~~The vector's magnitude and direction is best understood when the dislocation-bearing crystal structure is first visualized ''without'' the dislocation, that is,~~ the ~~''perfect'' crystal structure. In this [[perfect crystal~~]~~] structure, a rectangle whose lengths and widths are integer multiples of "a" (the [[Crystal structure#Unit cell\|unit cell]] length~~) is ~~drawn ''encompassing''~~ the ~~site of the original dislocation's origin~~. ~~Once this encompassing rectangle~~ is ~~drawn, the dislocation can be introduced.

The said rectangle could have one of its sides disjoined from the perpendicular side, severing the connection of the length and width line segments of the rectangle at~~ one ~~of the rectangle's corners, and displacing each [[line segment]] from each other~~. What ~~was once a rectangle before the dislocation was introduced~~ is ~~now an open geometric figure, whose opening defines the direction and magnitude of the Burgers vector~~. ~~Specifically, the breadth of the opening defines the magnitude of the Burgers vector,~~ and~~, when a set of fixed coordinates is introduced, an angle between the termini of the dislocated rectangle's length line segment~~ and ~~width line segment may be specified~~.

	~~The direction of the vector depends on the plane of dislocation, which is usually on the closest-packed plane of unit cell.~~
	~~The magnitude is usually represented by the equation:~~
	::<~~math~~>
	~~\\|\mathbf{b}\\|\ = \textstyle\frac{a}{2}\sqrt{h^2+k^2+l^2}~~

	~~where ''a'' is the unit cell length of the crystal, \|\|'''b'''\|\| is the magnitude of Burgers vector and h, k, and l are the components of the Burgers vector, '''b''' = <h k l~~>. In most metallic materials, the magnitude of the Burgers vector for a dislocation is of a magnitude equal to the interatomic spacing of the material, since a single dislocation will offset the crystal lattice by one close-packed crystallographic spacing unit.

Hi there, I am Andrew Berryhill. Mississippi is where her home is but her spouse wants them to move. Office supervising is exactly where her primary earnings comes from but she's currently applied for an additional one. One of the things she loves most is canoeing and she's been performing it for fairly a while.<br><br>Feel free to [http://myfusionprofits.com/groups/find-out-about-self-improvement-tips-here/ psychic readings online] visit my homepage :: free tarot [http://www.aseandate.com/index.php?m=member_profile&p=profile&id=13352970 accurate psychic readings] ([http://cspl.postech.ac.kr/zboard/Membersonly/144571 cspl.postech.ac.kr])
